Testing
Gloss, Haze and Surface Appearance Testing
Objective appearance evaluation of paint, coating, plastic and metal surfaces through 20°/60°/85° gloss, haze, DOI and RIQ measurements.
In short
Objective appearance evaluation of paint, coating, plastic and metal surfaces through 20°/60°/85° gloss, haze, DOI and RIQ measurements. Gloss, haze and surface appearance testing is performed with a Rhopoint IQ 20/60/85 appearance meter. Typical questions include orange peel, haze from micro-roughness, gloss loss after curing or weathering and within-batch consistency.
Gloss, haze and surface appearance testing is performed with a Rhopoint IQ 20/60/85 appearance meter. In addition to three-angle gloss measurement compatible with ISO 2813 and ASTM D523, the instrument reports reflection haze (ASTM E430), distinctness of image (DOI) and reflected image quality (RIQ) in a single reading, distinguishing surfaces that share the same gloss value yet look different to the eye. Typical questions include orange peel, haze from micro-roughness, gloss loss after curing or weathering and within-batch consistency. Specimens are assessed with multiple readings across different areas and compared against reference panels or specification limits. Main users are automotive paint and plastic part manufacturers, powder and coil coating producers, furniture and laminate makers, packaging and printing companies and consumer electronics enclosure manufacturers.

How it works
Request and scoping
Surface type, expected gloss range, measurement geometry, number of readings per specimen and comparison criteria are agreed.
Sample reception and preparation
Specimens are logged, cleaned of dust and fingerprints, conditioned to laboratory ambient and marked with measurement positions.
Measurement
The instrument is verified against its calibration standard; multiple gloss, haze and DOI readings are taken at the defined positions on each specimen.
Reporting
Results are presented in the standard analysis report; supporting technical documentation is shared on request.
